Harry has loads of doodles on the top of his left arm including a love heart, three nails and a coat hanger. We’re not too sure about the last two, maybe he needed to buy them and needed a reminder but couldn’t find any paper?

11. Louis’ doodles

Louis appears to have forgotten that he is actually a human, not a piece of paper and that tattoos last forever. On this one you can see his tattoo of a cup of tea which is based on his favourite line from their hit song Little Things. He also randomly has a stick man and a paper aeroplane.
